To all whom it may concern:

*Be it known that '1', Louis Home, a citizen (I); the United States, residin at Prairie dil out, in the count of St. Elixir and State? l, have invented cer Absorbing Spring-Suspension Devices, of which the following is a specification.

"This invention relates to acomhined shock [I absorbing spring suspension device.

The main object of the invention is to provide a shock absorbing suspension as vice so connecting a supported and supporting member that the jars and jolts received 15 by the latter will not be transmitted textile" former and which is especially designed for use in supporting a vehicle body z gainst shocks.

' Another object of the invention is to orevide a device ofthis character which is simple, cheap, and durable in construction and which may be readily ap lied to a vehicle and. when so applied wll absorb the jars and bumps so that the occupants of the vehicle will not be annoyed thereb i L 1 Withthese and other objects in View, the

invention consists in certain novel features of construction as hereinafter shown, described and claimed.

In the accompanying drawin Figure 1 represents a side e evatr'ion of a portion of a vehicle chassis with this improved device shown applied, part of the; chassis being broken away and the axle of V the vehicle shown in transverse section.

Fig. 2 is a plan view thereof, the chassis being shown in section.

Fig. 3 is a detail transverse section with parts broken out.

Fig. 4 is a. transverse section taken on the line 42 i of Fig. 1.

Fig. 5 is a similar view taken on the line of Fig. 1. Fig. 6 is a detail perspective view of one" 1 member of the device with parts broken out for convenience in illustration, and:

Fig. T is a detail sectional view taken on the line 7-7 of Fig. 9 with the chassis shown in elevation and partly broken out.

1h theiembodiment illustrated the member to he supported is shown in the form of a vehicle chassis C and the supporting member or-members constitute the two axles, one 0111 of which is shown at A.

he means for securing the device to the axle A comprises a housing 1 inverted U- sheped in cross sectionwhich fits over the t-f'p of the axle A here shown in the form 0 s11 I-heem end secured in position by meglns of fidiolts 2 which extend under the exit; A and up three ii the housing 1 as is shown clearly in Fig. 3"oeihg equipped with the usual nuts for holding them in operatingengagement. Pltttes or bars 3 extend across the ends of the housing 1 below theanle A and are secured tosaid housing by eans of bolts which extend through the ends of'the plates=3 andthrongh bearings 5 Formed at tthelewer ends oFthe housing by rolling said housing outwardly. also connect to the housing 1 a plurality of spring carrying rods6', 7, and 8, the'lower ends of which have bearing 9 for the passa e therethrough of the connecting bolts 4.

e rod'tiextends centrallyfrom the inner side of the housing-L1 toe point presently to be described, while the 8 are spaced latemil'y apart on the opposite side of the housing and located in planes outsidetheiplane'mm ied'bythe rod 6 and extend upwardly an outwardly and are connected withthe outer end of the chassis (I as shown in Fig. 1 by means of clamps or clips 10, two of which are shown, one arranged on each side of the side bar of the chassis C. Theseibraekets or clamps 10 are shown Lshaped inform with the long arms fliereof streddling the chassis and bolted thereto. said connecting oolt operating {LS spindles 11 'for (see Fig; 1), the short arms 12 on the lL-shaped brackets 10 project laterallv outward from the opposed sides of the chassis C and overliethe apertured ends of a crossbar-or pla-te' iii-which is carried by the outer end of a strip or plate 14. The ends of this plate orbar 1 3 project on opposite sides of the plate 14' and rods 7 and 3 These bolts rods 7 and of theplate 14 and operates to prevent anly through corresponding apertures in the arms 12 of the brackets 10 and are secured by nuts which are locked thereon by any suitable means, pins 13 being here shown passed through said nuts and through the outer ends of the rods (see Fig. 7).

The plate 14 is arran ed longitudinally under the? sidefbiri of the 'chassi si s'l'cmfiii iii Fig. 1 and is" secured at its outer end to th brackets 10 in the manner above tilescrihed derstood that any modifications within the scope of the claimed invention may be made in the construction without departing from the principle of the invention or sacrificing any of its advantages.

\Vhat I claim is 1- 1. A shock absorbing spring suspension mechaiiism comprising a bar adapted to be secured to a member to be supported and having one end provided on opposite sides while its inner end is boltedto one flange oii ithereot'i "with laterally extending apertured the channel iron chassis as shown in Fig. 1.

arms and further having its other end pro- A strap 16 is carried by the inner endbF- vided withadepending obliquely disposed the plate 14 on the lower face thereof and has :1 depending downwardly and forwardly inclined arm 17 which is aperturedto receive the inner upper endof therod Q vhich rod.

is secured to said bracket arm by a nut locked thereto by any suitable means. V y i Mounted on each of the rods (i, 7, and S are inner and outer coiled springs lSland 191cspectively. The outer spring heavier than the inner springl8'alidiwhich hear at their "inner ends against collars 15 carried by said rods and 'at their outer ends against the bracket arms 17 arid 13 respectively. coiled springs yieldingly oppose any, relative downward movement of the ends of the plate 14. A i U, A y

A heavy coiledspring is mounted on the upperface of the housing 1 between and theplate 1 1 being engaged at its opposite ends with studs 2-1 and 22 carried re s ectively b said housing 1, and plate it, t e stud 22 lieing secured to fandforming a part of a plate 23 carried bythe lower face vertical upward movement of, the a de from bqingctrans nitted to the vehicle body.

From the above description, it will be obvious,-that the plates 14 are usedto attach thedevices to the chassis C, and the ends oi rods 6, 7 andS slide upward against the, tens'ionot the coiled spningsl8 and 19 carried bysaid bars and this spring action in (onnect ion with the spring 29 operates to fectively cushion ,the vehicle body or other supported element and to absorb all shocks, which are received by the axle). and pre vent the transmission thereof to said vehi cle body or supported'elements. a

\Vhile the device is hereinyshownand de scribed as applied to a vehicle ,obxil usly it .i may be employed asa \shgclr absorbing spring suspension device in many places for connecting asupported member and supporting member thcrefon so that and jolts applied to the, supportingmember will have very little itany eilect i n causing up and down movement of the supported member. v

The preferred embodiment ofthe inventinn is disclosed in the drawings and set forth in the specification. but it will be an apertured arm, a housing adapted to be secured to an underlying supporting member, a coiled spring interposed between said bar and housing, a pair of rods pivotally connected at one end to the lowerend of said housin and each sli dably mounted at its outer and in a lateral arm, an inclined rod pivotally connected at its inner end to said housing and slidabl mounted at its outer end in said obliquely disposed apertured arm, securing means [on theouter ends of said arms, an inner and outer coiled spring mounted on each of said rods between said arms and the pivoted lower endsof the rod.

,2, A shock absorbing spring suspension mechanism comprising a bar adapted to be secured to a member to be supported an having one end provided on opposite sides thereof with laterally extending apertured arms and further having its other end pros vidcd with a depending obliquely disposed apertured arm, a housing adapted to be secured to an underlying supporting member, a coiled spring interposed between said bar and housing, a pair of rods pivotally con,-

nectcd, at one end to the lower end of said housing and each slidably mounted at its outer ends in a lateral arm, an inclined rod pivotally connected at its inner end to said housing and slidably mounted at its outer end in said obliquely disposed apertured arm, securing means on the outer ends of saidarms, an inner and outer coiled spring mounted on each of said rods between said arms and the pivoted lower ends of the rod,

guiding studs carried by the upper face of the housing and the lower face of said bar and cooperating with that spring interposed between the bar and the housing.

3. A shock absorbing spring suspension mechanism comprising a bar adapted to be secured to a member to be supported and having one end provided on opposite sides thereof with laterally extending apertured arms and further having its other end provided with a depending obliquely disposed apertured arm, a housing adapted to be secured to an underlying supporting member, a coiled spring interposed between said bar and housing, a pair of rods pivotally connected at one end to the lower end of said housing and each slidably mounted at its outer ends in a lateral arm, an inclined rod pivotally connected at its inner end to said housing and slidably mounted at its outer end in said obliquely disposed apertured arm, securing means on the outer ends of said arms, an inner and outer coiled spring mounted on each of said rods between said arms and the pivoted lower ends of the rod, and said bar having that end provided With 10 a lateral arm depending and extending at an outward inclination.

In testimony whereof, I afiix my signature.
